Abstract

A novel approach is proposed that satisfies all critical system requirements. The design is based on modification of a waveguide radiating element using high dielectric strength materials. The radiating element design is compatible with a range of high dielectric strength materials. The element exhibits very high overall aperture efficiency (in excess of 98%) with minimal dissipative losses in the order of .1 dB. It will be shown that the design is compatible with several high strength dielectric materials. A robust plan to manufacture the antenna is presented that takes into account manufacturing of the final article that needs to conform to the host vehicle. Based on the past success and studies done in support of preparation for this proposal we believe the overall approach is sound and the risk is reasonable for execution of the program and carrying through to phase 2 and ultimately an implemented production program is low. Broadband, conformal, high power antennas have direct application to EW platforms and electronic attack missions. The technology will directly support a number of ongoing DOD acquisition programs, including weapons and manned/unmanned aircraft. On the civilian side the need for broadband high power communications exists and the technology will resolve key issues. Commercial benefits include high data rate transfer from mobile platforms, both air and ground.
